Question

In the given figure, if AB || CD, ∠ APQ = 50° and ∠PRD = 130°, then find ∠QPR

Answer 1

AB || CD,

∠ APQ = 50°

∠PRD = 130°

in figure QP joins AB at P

and if we extend it

vertically opposite angles are equal

∠PRD is intersect CD line

Angle BPR +angle PRD = 50+130=180

so , it is a property of parallel and trsnsversal line property

thats why ,theQPR is straight line

so angleQPR makes 180 degree

it may help you
